How it is calculated
- ROI
- (revenue − spend) ÷ spend × 100%
- The profit each unit of spend brought back. Zero is break-even, negative is a loss.
- Earnings per click (EPC)
- revenue ÷ clicks
- Average earnings from one click. If EPC is above your click cost, the campaign is profitable.
- Conversion rate (CR)
- leads ÷ clicks × 100%
- The share of clicks that turned into a lead.
- Cost per lead (CPL)
- spend ÷ leads
- What one lead costs before approval.
- Approval rate
- approved leads ÷ leads × 100%
- The share of leads the advertiser accepted and paid for.
- Cost per approved lead (CPA)
- spend ÷ approved leads
- The real cost of a paid action. Compare it with the offer payout.
